Multi-Layer Discovery and Visualization
To address problems such as layer-specific network visibility and difficult fault locating, the NCE-based IP+optical solution leverages multi-layer topology discovery to automatically generate a 3D network view that shows resource, traffic, and fault information, helping to improve O&M efficiency.
Automated Multi-Layer Link Provisioning
Cross links are the bridge between IP and optical networks. After carriers deploy optical devices and resources, the optical network can support many potential multi-layer links. The IP network is aware of these potential multi-layer links and activates them on demand according to changes in IP traffic or protection requirements.
Multi-layer restoration by optical ASON (MLR-O) attempts to restore service paths through ASON rerouting. When a fault occurs, NCE (Super) dynamically computes protection paths based on available optical resources, protecting the network against multiple fiber cuts in addition to saving wavelength resources. For low-priority services that do not require fast IP-layer protection mechanisms, cost-effective MLR-O is an ideal choice.
Multi-Layer Analysis and Simulation
NCE (Super) can analyze the impact of optical node and link faults on IP tunnels and links through fault simulation and generate analysis reports, which helps minimize dependency on manual intervention and cutover accidents, improve network robustness, and simplify O&M.
NCE (Super) simplifies O&M by automatically optimizing network-wide service resources and policies based on multi-layer traffic information. Optimization can be performed according to either traffic status or latency. If network congestion occurs, NCE (Super) automatically performs multi-layer capacity expansion. If latency increases and the IP layer is unable to address this issue, NCE (Super) performs multi-layer bypassing.
